PDF javascript not working on Mobile - Android/ iOs

Foxit PDF Reader works for me , many thanks for that suggestion.

Have the following JS to change the colour of a field depending on the value.  Works well on PC, but won't work on in Adobe Reader on Android

var pres=this.getField("pressure").value;
var total=0;
var partial=0;

if (pres<101)
{
this.getField("result").value="FAIL";
this.getField("result").fillColor=color.red;
total=total+10
}
else if (pres>111)
{
this.getField("result").value="FAIL";
this.getField("result").fillColor=color.red;
total=total+10
}
else if (pres>=101 && pres<=111)
{
this.getField("result").value="PASS";
this.getField("result").fillColor=color.green;
}

that's bad news. I need it to work on both iOS and Android

Hi Bernd,

I use a simple switch statement which I placed under Custom Keystroke Script.

switch (event.change) {
    
        case "SELECT YOUR CITY":
            this.getField("Street").setItems(["SELECT YOUR STREET"]);
            break;    
		case "NEW YORK":
            this.getField("Street").setItems(["SELECT YOUR STREET","STREET 1", "STREET 2"]);
            break;    
		case "CHICAGO":
            this.getField("Street").setItems(["SELECT YOUR STREET","STREET 3", "STREET 4"]);
            break;    
.

}
